- the motor With the operation of the electric circuit control unit, the motor is rotated to drive the fan so as to introduce the air into the housing from the wind inlet and blow the air out of the housing via wind outlet grids.
- a negative ion generator, and a ceramic block are respectively provided at the rear and the front terminals of the motor voltage lowering unit.
- Each of the two terminals of the ceramic block is covered by an electric conducting metallic layer and a heat shield layer, and the ceramic block is fixed at its position outside the two heat shield layers with fixing means.
- the ceramic block is apt to crack, become frangible, or even completely break under an excessively high temperature.
- the motor voltage lowering unit is conventionally made of an electric heater wire enclosed in a flat mica envelope, the contact surface of the mica with the high temperature heater wire will be exfoliated after a long time operation.
- the mica in a high temperature produces poisonous, dissoluble, and in-expellable particles which are severely harmful to human health after inhaling into the lungs.
- a hair dryer according to claim 1 comprising a heat generating mechanism wherein the operating temperature of the ceramic block inside can be timely detected so as to protect the hair dryer from overheating thereby prolonging its lifespan.
- the present invention provides a beehive figured porous ceramic block in which a temperature sensor switch and an overheat protection fuse electrically connected with each other are axially disposed along a central main passage formed in the ceramic block so as to timely interrupt the power supply in the emergency of over-temperature.
- the present invention also utilizes a porous ceramic block as a motor voltage lowering element.
- the ceramic block serves the functions of stabilizing and lowering the motor voltage when it is electrically connected with the motor, such that the conventional detect of the mica envelope exfoliation due to overheating of motor voltage lowering element will no more happen again.
- the hair dryer according to the present invention has a housing 1 accommodating a fan 2, a motor 3, and a heat generating mechanism 4 in it.
- the heat generating mechanism 4 is composed of a first ceramic block 41, a second ceramic block 42, several electrically conducting reeds 43, 44 being attached to the two ceramic blocks 41, 42, and several heat shield rings 51, 52 attached to the aforesaid reeds, the whole structure is enclosed by an envelope 40.
- Both the first and second ceramic blocks 41 and 42 are provided with a number of beehive like through pores 411, 421, Vietnamese, and further have main passages 412 an 422 respectively formed axially at their center portions, and both passages 412, 422 are communicated with each other, an electrically conducting ring 53 is intercalated between the two ceramic blocks 41 and 42.
- the aforesaid electrically conducting reeds 43 and 44 are respectively attached to the outer ends of the ceramic blocks 41 and 42, the other sides of the reeds 43 and 44 are respectively necked by the aforesaid heat shield rings 51 and 52.
- a temperature sensor switch 61 and an overheat protective fuse 62 are inserted axially into the main passages 412 and 422 of the ceramic blocks 41 and 42.
- the temperature sensor switch 61 which being in connection with the overheat protective fuse 62 at its one end, is provided with a transversely emerged pawl 63 fixedly hooked onto a protruded eye lug 511 on the heat shield ring 51, while the end of the fuse 62 opposite to the switch 61 is fixedly connected to a first L shaped bracket 71 which being emerged its one end out of the heat generating mechanism and hidden the other end inside thereof.
- the electrically conducting ring 53 is configurated into an annular shape with a lead leg 531 radially extended from its hub, by so, the lead leg 531 is electrically in connection with the second L shaped bracket 72, and a contactor 532 is provided on its rim for in connection with the motor 3 using a conductor.
- the heat shield ring 51, the electrically conducting reed 43, the first ceramic block 41, the electrically conducting ring 53, the second ceramic block 42, the electrically conducting reed 44, and the heat shield ring 52 are assembled in order and enclosed with the envelope 40 bolted onto an envelope ring 410 at its inner side, the outer side thereof is for engaging with the L shaped brackets 71 and 72.
- the first ceramic block 41 serves as a heat generating element, while the second ceramic block 42 as a voltage lowering element, the outer end of the envelope ring 410 is engaged with the motor 3 with fixing means.
- the motor 3 and the heat generating mechanism 4 are put together as a whole hair dryer unit, being axially disposed respectively in the main passages 412 and 422 of the first and second ceramic blocks 41 and 42, the sensor switch 61 and fuse 62 are able to promptly and sensitively detect the variation of temperature in the ceramic blocks 41 and 42.
- the temperature sensor switch 61 and the overheat protective fuse 62 actuate to interrupt the power supply so as to protect the ceramic blocks 41 and 42.
- the aforesaid switch 61 and fuse 62 is usually connected in series, alternatively one of them is intermediately tapped out from the supply line.
- the electrically conducting reeds 43, 44 intercalated between the ceramic blocks 41, 42 and attached to their ends are all corrugated on their surfaces so as to stably support the ceramic bodies 41 and 42 with their surface cushion effect.
- the heat generated from the ceramic blocks 41, 42 can be promptly conducted via the beehive figured pores 411, 421 formed on the ceramic blocks 41, 42 with an excellent efficiency.
- the ceramic blocks 41, 42 are also energized to generate heat and emit the far infrared ray along with the wind blow of fan 2 driven by the motor 3.
- the number of the ceramic blocks 41 and 42 can be varied according to the power required by the hair dryer to meet the standards of different countries, that means it can be more than one.
